National Energy Conference 2011

The 2nd Annual National Energy Conference started in 4th to 6th of this week, I attended the Wednesday 5th event and the presentations were impressive.
There was a good number of exhibitors were in attendance to show their products in in the energy sector. The public attendance was good, though not many were there on that day.
The 3-day event was at KICC (Kenyatta International Conference Centre).

▲The Power Technics stand was the most impressive, they mounted a VAWT (Vertical Axis Wind Turbine) which was spinning perfectly. Their people at the stand were also helpful. This was a coincidence because I was on attachment there last year. Good work PTL

▲Geothermal Development Corporation, GDC had an impressive rig for drilling of steam at a well. This model was detailed and given again that I had gone for attachment there, I understood everything well. The person who modeled this, whoever you are, good work.

Another stand worth the mention was KETRACO-Kenya Electricity Transmission Company, a newly formed government corporation that is in charge of the transmission lines handed over from Kenya Power. The gentlemen who were there to explain were very informed and knew what they were saying. The stand looked presentable with a PC to show a GIS software for designing the transmission line network.

Recommendations

1. Lake Turkana Wind Power should have been there, that was the primary reason why I attended.
2. More exhibitors will increase public attendance.

To the event organizers, splendid work, keep up.
